A CT scan or computed tomography scan is a medical imaging technique used in radiology to get detailed images of the body noninvasively for diagnostic purposes.

CT scans can detect bone and joint problems, like complex bone fractures and tumors. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes. They show internal injuries and bleeding, such as those caused by a car accident.
